Proving out how a genetic trait is inherited and proving that a trait is inheritable are very different.

Frank. you proved without a doubt that the axanthic gene in kennerlyi is indeed inheritable. Meaning it can be passed down to offspring. When breeding 2 like animals, it is likely you will get like offspring.

This is where proving how it is inherited comes into play. In other words, proving out the genetics.

You were indeed fortunate enough to have started with a pair of axanthics. A situation that rarely if ever occurs in captivity. This is why breeding a visual to a normal wild type is the first step in proving out a morph in most cases. It does not matter which step is taken first. However they are two equally important steps when trying to prove a morphs genetic inheritance.

You have established that breeding axanthic to axanthic produces more axanthics. This is no longer up for debate. Also, no one can debate the fact that these are indeed the first of their kind to be reproduced in a captive setting. I also never saw anyone try to say otherwise.

Breeding a visual to a normal will produce all wild type normals which has been established by Jon Roylance.

If breeding two normals from that pairing yields axanthic offspring, you will then know how the trait is being passed down to the next generation. Anything else is just a guess no matter how educated it may be. I am certain that the axanthic in kennerlyi is recessive, however, it is still just my guess and has yet to be proven.

I see no problem producing 100% hets. It is when people stupidly produce 66% and 50% hets. That can cause a crap storm.
